Aggiornamento docker-compose.yml per configurazione attuale

- Cambiata immagine: gitea.home-nas-ds.org/alessio/docker-voltronic-homeassistant:latest
- Aggiunta password MQTT corretta (non più placeholder)
- Aggiunto volume voltronic-cache per persistenza discovery
- Commentato watchtower (opzionale)
- Corretti commenti per chiarire uso ENV variables:
  * ENV sovrascrivono mqtt.json all'avvio automaticamente
  * Config volume mantiene calibration e buffer sizes
  * Cache volume evita re-discovery ad ogni restart
- Dockerfile build option usa multiarch invece di dev
